SPECIFICATION forming part of Letters Patent No. 767,439, dated August16, 1904. Application filed May 9, 1904:. Serial No. 207,158. (Nomodel.)

To ctZZ whom it may concern.-

Be it known that I, HERMANN XVALTHER REINHOLD, a subject of the King ofPrussia, and a resident of Dusseldorf. Germany, have invented a certainnew and Improved Cable- Clip for Suspended Cable-Railways, of which thefollowing is a specification.

This invention relates to an improved cableclip for use with thosesuspended cable-railways in which the weight of the suspended trolleycauses the cable to be gripped,whereas the cable is released when thesaid weight ceases to act on the clip.

In the improved clip a lever with arms .of unequal lengths is arrangedbetween a vertical slide supporting the weight of the trolley and ahorizontally-movable clamping cheek or clip arranged in the running-gearof the trolley, so that the movement of the vertical slide istransmitted to the clip with increased force. This allows of providingthe vertical slide with inclined, horizontal, curved, or angularguide-slots, flanges, or the like for operating the double-armed lever.The increased clamping effect due to the lever also allows of using theclip for cable-railways in which the cable is gripped at or about thelevel of the wheel-axles to prevent the tilting of the trolley. Thecombination of the clip and lever also allows of gripping the cable ateither side of the running-gear, as req uired-that is to say, thetrolley need not be turned at the end of the track in order to returnalong the second cable. The arrangement also allows of negotiatingcurves of the track without uncoupling the trolley from the cable.

The invention is illustrated in the annexed drawings, in which Figure 1is a vertical section on the line A B of Fig. 2, showing the simplestform of the clip and running-gear. Fig. 2 is a vertical section on theline C D of Fig. 1, and Fig. 3 a horizontal section on the line E F ofFig. 2. Fig. 4 is a section corresponding to that shown in Fig. 2, butillustrating a modification of the device which allows of gripping thecable at either side of the running-gear. Figs. 5 and 6 are a rear Viewand plan view, respectively, illustrating the passage of a curve withthe clip shown in Fig. 4. Fig. 7 is an elevation illustrating theinvention as applied to a cable-railway in which the traction-cable isarranged below the supporting-cable. Fig. 8 is a vertical section on theline G H of Fig. 7.

Between the side plates 1 of the runninggear is arranged the slide 2, towhich the suspensory device 4 of the trolley is connected by means ofthe bolt 3. The slide 2 is vertically guided in the usual manner and isprovided with guides 5, the purpose of which is to operate the clip orclamping-cheek 6 by means of the lever 7 when the slide 2 is pulleddownward or lifted. The longer arm of the lever 7 is provided for thispurpose with a small roller or a pin 8, engaging between said guides 5.

As already mentioned, the use of the lever 7 allows of opening andclosing the clip by means of inclined guides or slots of the kind shownin Figs. 2 and 4 or by means of horizontal guides, as shown in Fig. 8.The guides can also be curved or angular. The difference as regardseffect is only that if the slide 2 is provided with horizontal guides orgrooves it must travel through a longer distance than if provided withcurved or inclined guides, but will have only very slight friction toovercome. Angular and curved guides combine the two advantages of shortstroke and slight friction and also have the advantage that the openingoperation of the clip is first rapid and then more gradual, so that thewear and tear of the clip and the traction-cable is less than withinclined and horizontal guides.

The shorter arm of the lever 7 engages into a suitable aperture in thehorizontal part 6 of the clip 6, as shown in Fig. 2. The said part 6 isrectilinearly movable in the bearings 9 and 10, which are integral withthe side plates 1 at or about the level of the wheelaxles 11.

The bearing 10 is enlarged to receive the pivot 12 of the lever 7, andthe slide 2 is provided with a vertical slot for the horizontal part 6of the clip.

When the weight of the trolley pulls down the slide 2, thetraction-cable 13 is pressed by the clip 6 against the outer surface ofthe bearing 9, the movement of the said slide being transmitted withincreased force to the 1 clip for causing the latter to grip thetractionclip by means of the guides 5 and lever i.

In the form of construction shown in Fig. 1 a fixed clip 15 is providedwhich is integral with the bearing or frame part for the purpose ofcoupling the trolley with the tractioncable when traveling on curves orduring the return journey, the cable being gripped by the end of thepart 6 and the clip 15, as shown in Figs. and (3. During the journey inone direction, Figs. 5 and 6, lefthand side, the clip 6 grips the cable13, passing round the pulley 16, and during the return journey, Figs. 5and 6, right-hand side, the clip grips the cable.

For cable-railways in which the tractioncable 13 is arranged below thesupporting-cable .18 the form of the device shown in Figs. 7 and 8 isused. In this form of construction one side plate 1 of the vframeprojects down ward to a considerable extent and is provided at its lowerend with the gripper mechanism. In this case the supporting-bolt Z) isnot directly connected to the slide L, but to a slide 2, which isconnected to the slide 2 by means of the rod 19. It is obvious that thisform of construction can be executed exactly like that of Fig. 41 andthat this gripper mechanism can be combined with that of Figs. 2 and ar-that is to say, the slide 2 and the parts 1 can be constructed exactlyas shown in Figs. 1 to 4, the slide 2 being, however, also connected toa slide 2 above same in the manner shown in Figs. 7 and 8 or a similarmanner, the slide 2 being provided with the supporting-bolt. Acombination of this kind can be used for c; ble-railways withtraction-cables above or below the supporting-cable and for tracks inwhich the traction-cable is partly below and partly above thesupporting-cable.

I declare that what I claim is- 1. In a suspension cable-railway thecombination with a supporting-cable, a traction-cable and a suspendedtrolley, of a slide adapted to be operated by the weight of the latter,a horizontally movable clip traversing said slide and means intermediatethe slide and cable with increased force on movement of said slide inone direction substantially as described.

2. In a suspension cable-railway the combination with asupporting-cable, a traction-eable and a suspended trolley 01 averticallyguided slide carried by the latter and adapted to be operatedby the weight thereof, a horizontally-movable clip traversing said slideand meansintermediate the slide and clip for causing the latter to gripthe traction-cable with increased force adjacent the plane of thetrolley-wheel axles on downward movement of said slide, substantially asdescribed.

3. In a suspension cable-railway the combination with asupporting-cable, a traction-cable and a suspended trolley, of averticallyguided slide adapted to be operated by the weight of the saidtrolley and provided with a guideway, a horizontal]y-movable cliptraversing said slide and a lever having arms engaging said guideway andclip respectively and adapted to cause the latter to grip thetraction-cable with increased force on downward movement of said. slide,substantially as described.

4. In a suspension cable-railway the combination with asupporting-cable, a traction-cable, and a suspended trolley, of averticallyguided slide adapted to be operated by the weight of saidtrolley, a horizontally-movable clip traversing said slide, meansintermediate the slide and clip for causing the latter to grip at oneend the traction-cable with increased force on downward movement of saidslide and a second clip integral with the trolley and between which andthe other end of the movable clip the traction-cable is also adapted tobe gripped substantially as described.

In witness whereof I have signed this specification in the presence oftwo witnesses.
